Butt Weld Fittings

Long Radius 90 Degree Elbow

90 Degree Long Radius Elbow

An elbow is a pipe fitting that is used as a connection point between two lengths of pipes to produce a change in the direction of flow in the pipe, usually at an angle of 90°, 45°, or 180°. Butt weld long radius 90 degree elbow is used for 90 degree turn on piping in butt weld piping system.  The long radius elbows have a center to end distance that is 1.5 times the NPS in inches (R=1.5D). Long radius elbows are preferred when space is available and flow is more critical.
